Uncovering Non-24 in your patients who are totally blind

What to look for1,2

  • Complaints of excessive sleepiness, insomnia, or both
  • Decreased social and occupational functioning
  • Sleep disturbance that is not better explained by another current sleep disorder, medical or neurological disorder, mental disorder, medication use, or substance use disorder

Important diagnostic information for Non-24

ICD-10
G47.24
Circadian rhythm sleep disorder, free-running type (Non-24)3
DSM-5
Circadian rhythm sleep-wake disorder, Non-24-hour sleep-wake type2

A. A persistent or recurrent pattern of sleep disruption that is primarily due to an alteration of the circadian system or to a misalignment between the endogenous circadian rhythm and the sleep-wake schedule required by an individual’s physical environment or social or professional schedule.

B. The sleep disruption leads to excessive sleepiness or insomnia, or both.

C. The sleep disturbance causes clinically significant distress or impairment in social, occupational, and other important areas of functioning.

If your patients who are totally blind experience excessive sleepiness,
insomnia, or both, you should consider Non-24

Healthcare Provider Important Safety Information

The most common adverse reactions (incidence >5% and at least twice as high on HETLIOZ® (tasimelteon) than on placebo) were headache, increased alanine aminotransferase, nightmares or unusual dreams, and upper respiratory or urinary tract infection. The risk of adverse reactions may be greater in elderly (>65 years) patients than younger patients because exposure to HETLIOZ® is increased by approximately 2-fold compared with younger patients.

Indication

HETLIOZ® (tasimelteon) capsules are indicated for the treatment of Non-24-Hour Sleep-Wake Disorder (Non-24) in adults and nighttime sleep disturbances in Smith-Magenis Syndrome (SMS) in patients 16 years of age and older. HETLIOZ LQ® oral suspension is indicated for the treatment of nighttime sleep disturbances in SMS in patients 3 to 15 years of age.

Important Safety Information

  • HETLIOZ® may cause somnolence: After taking HETLIOZ®, patients should limit their activity to preparing for going to bed, because HETLIOZ® can potentially impair the performance of activities requiring complete mental alertness.
  • The most common adverse reactions (incidence >5% and at least twice as high on HETLIOZ® than on placebo) were headache, increased alanine aminotransferase, nightmares or unusual dreams, and upper respiratory or urinary tract infection. The risk of adverse reactions may be greater in elderly (>65 years) patients than younger patients because exposure to HETLIOZ® is increased by approximately 2-fold compared with younger patients.Adverse reactions were similar in patients treated for Non-24 and patients with SMS treated for nighttime sleep disturbances. Adverse reactions were also similar in pediatric patients (3 years to 15 years) who received HETLIOZ LQ® oral suspension, and patients ≥16 years of age who received HETLIOZ capsules
  • Use of HETLIOZ® should be avoided in combination with fluvoxamine or other strong CYP1A2 inhibitors, because of a potentially large increase in exposure of HETLIOZ®, and a greater risk of adverse reactions. HETLIOZ® should be avoided in combination with rifampin or other CYP3A4 inducers, because of a potentially large decrease in exposure of HETLIOZ®, with reduced efficacy.
  • There are no adequate and well-controlled studies of HETLIOZ® in pregnant women. Based on animal data, HETLIOZ® may cause fetal harm. Caution should be exercised when HETLIOZ® is administered to a nursing woman.
  • HETLIOZ® has not been studied in patients with severe hepatic impairment and is not recommended in these patients.
  • The safety and effectiveness of HETLIOZ® for the treatment of Non-24 in pediatric patients have not been established. The safety and effectiveness of HETLIOZ LQ® oral suspension for the treatment of nighttime sleep disturbances in SMS have been established in pediatric patients 3 years and older.
